So far what I've found is that it's not a very common part as it is a series of cups, a plastic isolator and soldered horn wire. The balls, race and all the cups in mine are actually fine it's the plastic between the bearing assembly and outer cup that disintegrated. The spring then pushed the bearing assembly out of the main cup and down the column. I'm lucky it didn't separate and spill the balls.
Mostly I'm just worried the plastic in the NOS piece might be brittle and the quality of the repop is super cheap.
You can see how mine broke, pushed through and how I extracted the pieces.
